X-Ray testing

To the right are examples of X-Ray results. Both contain an X-Ray image and the Manufacturer’s pin-out information describing what each termination should do.

At the top, a pass result. In this one the Manufacturer describes all terminations as having purposes. In the X-Ray we can see that there are no missing connections.

At the bottom, a fail result. Here, the Manufacturer describes some terminations as having purposes (GND, VDD) that don’t have connections when viewed under X-Ray. It also

shows terminations that shouldn’t have connections (N/C) with connections present in the actual part.
